CENTRIFUGAL MACHINE.

To (Ill who u fling concern:

lie it known that l, Enwann D. lMACKIN- 'rosn, a citizen of the ,llnited States, residing at lh-ooklyin in the county of Kings and the State of New York, have invented a new and useful Improvement in Centrifugal Machines, of which the following is a specificat-ion.

My invention relates to gal machines driven by motors.

The object of my invention is to apply motive power, other than by a belt, to a hanging and swingablc centrifugal machine.

Referring to the accom a-nying drawing, forming partof this specification:

Figure l is an elevation, partly in section, of my improvement.

Fig. 2 is a top plan of one of the details. a is the spindle of the centrifugal machine fixed to a huh I). This hub is rotatively supported by a bearing consisting of a nonrotating cup 1; with non-rotating ball races (1, a rotating hall race a, and balls 7' between the races, the huh I) resting on the rotating ball race and the cup r; supporting all The cup rests upon a table g which is tiltable, in any direction, in a socket It held by a support i.

The support 1' is formed with a ring part j which closely confines the upper part of the hearing laterally but clears it enough to allow it. to swing to the position shown by the broken lines. the table 9 tilting to accommodate itself to the position taken by the bearing. The tilting of the table takes place about the center and the bearing swings about the center 0 at the upper part thereof.

A flange k is formed integrally with the huh I) and has lugs Z, at diametrically opposite sides of theflange, and forming part of it. which loosely engage an H-shaped link m, there being lugs both in front of and behind the link, to form forks, closely embracing it. This link is pivoted. at n n, to

hanging centrifudn'ect connected 'the head 0, to swing about a horizontal axis,

and the head is fixed to the spindle p of a non-swingable motor.

The part of the flange which carries the lugs is in the form of a ring depending from the horizontal part'of thesaid flange and closely surrounding, but. not touching, the support i. One oh cct in forming the flange Specification of Letters Patent.

, to s. s. nsrwoarz n, or NEW YORK, Ann sm'm M.

with this depending ring is to keep ,and

dust from getting to the-bearing. v

In operation, the centrifugal qinachine swings, when it swings at all, about. the center 0' while the swingable H-shaped link acts as an equalizer to transmit equal power to the lugs Z at the two sides of the flange 10. This link, having once swung into contact with the lugs at the two sides of the flange, does not thereafter swing when the centrifugal machine swings. This is because it engages the lugs at the level of the point about which the centrifugal machine swings, viz: center 0'. i

I claim:

1 A swingable bearing, a vertical shaft supported thereby, a tiltable table ,underneath the bearing and supporting it, and a stationary =rnig confining the upper part of the hearing and restraining'the said upper part from moving laterally to any considerable extent but not rest-raining it from swinging.

2. A swingahle bearing. a vertical shaft supported thereby, a tiltable table underneath the bearing and supporting it, a stationary ring confining the upper part of the bearing and restraining the said upper part from moving laterally to any considerable extent but not restraining it from swinging. and a flange supported by the bearing and closely surrounding the stationary ring without touching it.

3. A non-swingable vertical shaft, a
